SPECIFICATION orming part of Letters Patent No. 369,656, dated September 6, lll887.

Application filed April 30, 1887. Serial No. 236.613. (No model.) Y

To all whom may concern:

Be it known that I, ALBERT L. PURDY, of ellsville, in the county of Allegany and State of New York, have invented new and useful Improvements in Suspender-Buckles, of which the following is a specification.

This invention relates to an improvement in that class of suspendenbuckles which are usually construct-ed of wire and provided with a [O pivoted clamping-frame, whereby the buckle is adj ustably secured to the suspendenstrap, and a hook'whereby the buckle is attached to the loop which connects the ends of the suspender.

I My invention has for its object to provide a simple buckle of this character which can be conveniently adjusted on the-suspender and which can be produced at comparatively small expense. j

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l represents a front elevation of my improved buckle applied to a suspender-strap. Fig. 2

represents an end view thereof, showing the buckle in an open position for receiving the suspender-strap. Fig. 3 is a vertical longitudinal section of the buckle. Fig. 4 is a rear 3o elevation of the buckle, with the suspenderstrap shown in dotted lines. Fig. 5 is a detached perspective view of the rear frame of the buckle, partly in section. Fig. 6 is a similar view of the pivoted clamping-frame. Fig.

7 is a perspective view of the loop attached to the suspender-ends. Fig. Sis a rear elevation of a modilied form of the buckle. Fig. 9 is a perspective View of the rear frame of the buckle represented in Fig. 8.

.to Like letters of reference refer to like parts in the several figures.

A represents the suspender strap or webbing, to which the buckle is adjustably secured, and B represents the suspender-ends,

1,5 which are provided with a loop, B', whereby they are attached to the suspender-buckle.

C represents the rear frame of the buckle, and D the clamping bail or frame, whiehis pivoted to the frame C and provided with a hook, d, over which engages the loop B of the suspender-ends. The trame O is of rectangular form and composed of side bars, c, and connecting cross-bars c c2, preferably formed of a single piece of wire, the ends of the wire being united near the center of the upper 5 cross-bar, c', by a metallic sleeve or thimble, c3. The side bars are provided witheyes or loops c", through which the upper cross-bar ot' the clamping-frame is inserted7 whereby the clamping-frame is pivoted to the rear frame of fo the buckle. The elampingframe D, with its hook d, is also preferably formed of a single piece of wire, and is composed ot' an-upper crossbar, d', a lower cross-bar, d2, connecting side bars, d, and a downwardly-projecting spring-arm, d4. The hook d of the clampingframe is formed in the center of the lower cross-bar, d2, and the spring-arm d4 extends downwardly from the center of the upper cross-bar, d', with its lower end projecting in- 70 wardly between the inner vertical sides ofthe hook, as clearly shown in Fig. 6. The upper cross-bar, d', is iuclosed in a metallic sleeve or thimble, e.

frepresents teeth or serrations formed on the sleeve or thimble c and arranged so as to project into the space between the two crossbars of the frame C and embed themselves in the webbing of the suspender-strap when the clampingbail D is swung down upon the sus- 8o penderstrap, as shown in Figs. l and 8. The upper cross-bar, cZ, which carries the teeth f, lies centrally between the crossbars of the frame C and depresses the webbing A into the space between said cross-bars, thereby form- S5 ing a bend in the webbing and firmly securing the same to the buckle. The pivoted clamping-frame D is held in a closed position against the front side of the suspender-strap by the downward pressure exerted on its hook d by 9o the loop B of the suspenderends. The portion of the upper cross-bar, d', that carries the serrations or teeth f is preferably bent backward or depressed a short distance below the plane or" the end portions of said bars, so that 9 5 the serrations or teeth f will have an eccentric movement when the clamping-frame is swung on its pivots or eyes c, and will cause the sus-` pender-strap to be forced inwardly between the crossbars of the rear frame. cross-bar, c2, of the frame is preferably provided with a loose thimble or roller, g, and the webbing or suspender-strap is clamped between the -roller and the serrated bar of the frame C, as the latter is swung downwardly, until the lteeth of the serrated bar are embedded in the webbing. If preferred, the rear frame, C, may be provided with a metallic plate, h, which is formed in one piece with the thimbles on the cross-bars of the frame, and forms a closed back for the frame, as shown in Figs. 8 and 9. In this construction the webbing is clamped against the plate h, between the cross-bars of the frame C, by the serrated bar of the clamping-frame.

In applying my improved buckle to the suspender-strap the clamping-frame D is raised to the position shown in Fig. 2, whereby the serrations or teeth f on the cross-bar of the clampingframe are turned so as to point outwardly and present a smooth unobstructed passage between the frame C and the adjacent side of the upper cross-bar of the clampingfrapge. The suspender-strap can now be readily inserted between the frame C and the serrated cross-bar of the clamping-frame and the buckle adjusted on the suspender. When the buckle has been adjusted to the proper position', it is readily locked or secured in place by swinging the clamping-frame C downwardly, whereby the serrations on the crossbar of the clamping-frame are embedded in the suspender as the latter is clamped or wedged between the frame O and the clamping-frame. The buckle is held in this position by engaging the loop B over the hook d of the clamping-frame. The spring-arm d4 projects into the mouth of the hook dand prevents the loop from becoming disengaged therefrom. Upon pressing inwardly on the Spring-arm d4 the hook d can be readiljT disengaged from the The lower loop. The lower end of the spring-arm d4 is bent inwardly, so that the spring will be delected inwardly and allow the loop B to be disengaged from the hook d by pushing upwardly on the loop. The loop B is also formed of a single piece of wire, and its lower crossbar is provided with a loose sleeve or roller, t, which incloses the ends of the wire, as shown in Fig. 7.

My improved buckle is very simple in construction, it can be readily applied and adjusted on thesuspender, and can be produced at comparatively small expense.

I claim as my invention- 1. The combination, with the main frame provided with cross-bars c c2 and eyes c, arranged between said cross-bars and formed by looping in the side portions of thevframe, of a clamping-frame, D, pivoted in the eyesc* and provided with a serrated cross-bar, f, projecting into the space between the cross-bars c c, a hook, d, and a spring-arm, d4, projecting into the mouth of the hook, substantially as set forth.

2. The combination, with the buckle-frame C and the pivotedclamp-bail D, provided with a hook, d, ofa spring-arm, d4, secured to the clamping-bail and projecting into the mouth of the -hook d, substantially as set forth.

. 3. The combination, with the buckle-frame C, composed of cross-bars c c2 and side bars provided with eyes c4, formed by loopingiin the side bars ofthe frame, of a olampingbail, D, pivoted in the eyes 0*. and provided with a serrated cross-bar, f, the portion-of the latter carrying the serrations being depressed below the plane of the eyes, substantially as set forth.

Witness my hand this 26th day of April, 1887. ALBERT L. PURDY.
